To all whom it may concern.

Be it known that I, EDWARD WILLIAM BAR- RATT, manufacturer, a subject of the King of Great Britain, residing at 1 Tower Terrace, Wood Green,in the county of Middlesex, England, have invented certain new and useful Improvements Relating to the Manufacture of Sweetmeats or Similar Articles of Confectioncry, of which the following is a specification.

This invention relates to the manufacture of sweetmeats and similar articles of confectionery,and has particular reference to the operationknown as pulling sugar or candy.

The chief object of the present invention is to devise a simple and comparatively inexpensive machine for effecting this operation. I provide two rigid bars, which I term stationary pulling-bars, and a movable bar, which I term a traveling pulling-bar. This traveling pulling-bar is by the action of two pairs of rotary arms caused to revolve about the stationary pulling-bars in a course somewhat resembling the figure 8 lying on one of its sides, this result being attained according to my present invention by arranging the rotary arms of each pair on opposite sides of the machine,so that each pair can support opposite ends of the traveling pullingbar, The said two pairs of rotary arms are caused to revolve about their axes, and their ends describe circular paths around the stationary pulling-bars, which are held rigidly inplace by fixed arms arranged opposite one another in pairs, the paths of the said ends of the rotary arms closely approaching or touching one another once during each of their revolutions at a point approximately diametrically opposite the axis of each of the stationary pulling-bars. The revolutions of the rotary arms are in opposite directions, and the speed of revolution varies, so that each time one pair of the said arms passes the other pair the traveling, pulling-bar will be caught by the pair of rotary arms of greater speed and transferred thereto from the other pair, suitable means, such as a catch arrangement, being provided for retaining the traveling pulling-bar in the pair of arms which for the time being carry it and for liberating it when the time arrives for it to be transferred to the other pair of arms.

In the accompanying drawings, Figure 1 is a side elevation of the sugar-pulling machine:

Fig. 2 is an end elevation, and Fig. 3 a plan, of the same. Fig. 4 is a detail sectional view, 011 an enlarged scale, showing the catch arrangement for locking and unlocking the traveling pulling-bar to and from the rotary arms.

A is the base of the machine, carrying upwardly-projecting standards orsupports A A A A arranged in pairs on opposite sides of the machine. These standards are provided at their upper ends with short inwardlyprojecting stationary axles a a a a furnished with rotary sleeves having radial arms a a a a The radial arms have recessed extremities for the reception of the ends of the traveling pulling-bar B. Each radial arm is furnished with the aforesaid catch arrangement, which in the example illustrated comprises a sliding plate or finger a, Fig. 4, having guide-slots a a through which pass screws a for retaining said finger in place and permitting it toslide. The inner end of the finger is connected by a link a with a lever a transversely mounted on the rotary arm. The free end of this lever a is by the action of a spring a pressed against a cam a", fixed on each of the stationary axles a a, so that as the rotary radial arms revolve the said cam will cause the finger a to slide to and fro over the entrance to the recessed end of the said radial arms, so as to open and close the same. The shape of the said cams is such that the said fingers are kept in their closing position until the ends of the pairs of radial arms approach each other in their revolution, when said fingers are withdrawn to un cover the recessed ends and permit the trans ference of the traveling pulling-bar from one pair of radial arms to the other, which opera tion occurs as said ends pass each other. In order to enable this transference to take place, the outer or recessed ends of one pair of the radial arms must pass the outer or recessed ends of the other pair. The outer ends of the pair of radial arms a are therefore bent or otherwise formed in such manner as to move in a different plane to that of the other pair a, as shown in Figs. 2 and 3. The said radial arms a a are adapted to travel at different speeds as they pass each other, so as to enable the one of greater speed to overtake the other and in so doing to remove the traveling pulling-bar l3 therefrom. For this purpose the sleeves carrying the radial arms are furnished with pulleys or sprocket-wheels a which by means of endless bands or chains a are geared with pulleys or sprocketwheels (L12, mounted on transverse shafts (L 0 situated below the base of the machine, the said pulleys or sprocket-wheels (0 being twice the diameter of the pulleys or sprocketwheels a and therefore imparting thereto and to the rotary arms twice the number of revolutions of the pulleys or sprocketwheels (W. The shafts a are geared together by a pair of toothed wheels at a, which are eccentrically mounted on their shafts, as shown in Fig. 1. One of the said shafts also carries a toothed wheel (1 Fig. 2, to which motion is imparted from the main drivingshaft a by a toothed pinion a, this main shaft being also situated beneath the base of the machine. By means of the above-described gearing a a a rotary motion is imparted to the pairs of radial arms in opposite directions, as represented by the arrows in Fig. 1, and an unequal speed is imparted to the shafts a (0 and therefore to the arms, by the eccentric gear-wheels a a, the greatest difference in the speed of the radial arms taking place when the ends of one pair pass those of the other pair.

0 C are the stationary pulling-bars, which are fixed in arms 0 0 forming part of the fixed axles a a said arms projecting horizontally from the axles in opposite directions, as represented in Figs. 1 and 3. The length of these arms is such that the stationary pulling-bars lie within the circular path described by the ends of the radial arms a a, so that as said radial arms revolve and alternately carry the traveling pulling -bar from one to another, as above explained, the pulling of the sugar or candy will be effected, as is well understood in connection with sugar-pulling machines, The aforesaid traveling pullingbar has adjustable collars Z) Z), which operate to keep the sugar or candy from extending beyond the ends of said pulling-bar during the working of the machine. These collars can be set closer to or farther from each other, in accordance with the quantity of sugar or candy to be treated in the machine. Near the ends of the said traveling pulling-bar are enlargements or bosses b b, which serve as guides for keeping the said pulling-bar from undue longitudinal movement in the recessed ends of the rotary arms a a In order to avoid the too-rapid cooling of the sugar or candy during the pulling operation, I may supply steam or other hot fluid to the stationary pulling-bars O, which are then made hollow and connected by means of passages 0 0 Fig. 4:, in the arms 0 and the axles a with pipes 0 The said hot fluid would pass in and through one of the stationary pulling-bars and then pass (by a connecting-pipe) across to and through the other stationary pulling-bar, whence it would pass back to the source of supply. A constant circulation of the hot fluid would in that way be provided.

If desired, a removable tray may be provided on the bed of the machine, so that in the event of the'su gar or candy dropping from the pulling-bars during the working of the machine it Will fall onto said tray, which can be readily withdrawn with the sugar or candy and the latter be picked up by the machine attendant for replacing onto the pulling-bars without the attendant subjecting himself to danger of being injured by the machine.

' I wish it to be understood that I do not limit myself to the specific means hereinbefore described for locking and unlocking the traveling pulling-bar to and from the radial arms a a, as any other suitable means may be employed for this purpose.
